Shoring brace for manhole by NTS

Hydraulic Shoring

Hydraulic shores are the quickest way to shore a trench. They are designed to prevent cave-ins in all but the most unstable soil conditions by supporting the sidewalls of the trench through hydraulic pressure. All vertical shores are installed and removed from the top of the trench. Hydraulic vertical shores are lightweight shoring devices that can be installed by a single worker as fast as the trench is excavated.
